28-30 October 2005 Uwe Müller & Manuel Klatt, Electronic Publishing Group, CMS / UB Humboldt-Universität zu Berlin

SCOPE:

An XML Based Publication PlatformService Core for Open Publishing Environments


Background

• Humboldt University: 800 – 1.000 dissertations / year• Germany: duty to publish dissertations• Humboldt U.: ~ ¼ dissertations published electronically• conference proceedings• series (university series, preprint series, technical

reports …)• electronic journals• Open Access campaign (Pre- / Postprints)

• XML as central strategy


SCOPE:




SCOPE:



Why XML?

• Standardized format• Long term preservation• easily convertible to

– presentation formats (HTML, PDF)

– other XML structures• qualified full text retrieval • contains structural and

contextual information – in a machine readable format

Office documentOffice document


XMLXML


SCOPE:



XML: Restrictions to deal with

• XML source does not contain layout information• rather linear structure• XML is not used as Authoring System

– authors use their 'own' systems• Microsoft Word• LaTeX• Open Office / Star Office• Framemaker• Word Perfect


SCOPE:



How to overjump the gap?

• get the authors where they are …• instructions and guidelines for authors

– usage of style files (e.g., dissertation-hu.dot) – manuals, support hotline, regular courses

• different conversion processes– SGML author (plug in for MS Word <= 97) – Open Office / Star Office

• exploit genuine XML format

– MS Office 2003XML according to DiML DTD– common pitfalls: tables, pictures


SCOPE:




SCOPE:



Conversion Process Using OO (Example)

SCOPE:



Principal Structure of a DiML document<etd>

<front>..title...author...abstract...</front> <body> <chapter> <section> ... </body> <back>..bibliography...appendix...vita...</back>

</etd>


SCOPE:



From flat structure to Hierarchy• only two types of styles in Word

– paragraph styles– character styles

• e.g., in case of the first occurring Heading 1 paragraph style the converter has to know– Heading 1 is the beginning of a chapter– Heading 1 implies a head element– the element chapter can only occur in body

</front><body><chapter>

<head id="anyID">Introduction</head>


SCOPE:




SCOPE:



One Core – Multiple Views

• HTML generation (static or dynamic)– performance problems with XSLT and huge

documents– solution: division of XML sources into components

(easier and fast to process)• PDF + Print on Demand (http://www.proprint-service.de)• Current problems

– changing Office systems and versions• ongoing implementations and adaptations necessary• but: might be restricted to XSL coding


SCOPE:



XML Based Publishing

characterized by

• complex processes and workflows

• many dependent tools and manual work steps

• relatively high human effort

• different processes for different publications, but with a lot of equal steps and properties

• ongoing development – changing versions

• Basic Idea:1. Raise concrete process description to an abstract level2. Implement integrated workflow system


SCOPE:



SCOPE

Service

Core for

Open

Publishing

Environments

• support for authors and editorsprovide an integrated publishing platform

• XML based • aiming at technological aspect of

publishing processes• tool management• platform for distributed publishing• generic framework for different

processes


SCOPE:



SCOPE goals• elementary Publication Components (Document Models,

Authoring Tools, Conversion Scripts, Digital Signatures …)• Management System to organize and administer the Publication

Components– modelling of relations and dependencies– version management

• Publishing System– management and storage of documents

• Workflow System– modelling of recurrent processes (technical validation,

conversion processes, reviewing, conference organisation …)


SCOPE:



Authoring Tools

(e.g. Document Style)

Validation and Correction Tools

(e.g. Word Macros)

Conversion and Tranformation Tools

(XSLT, Perl-Scripts, Java, ...)

Publication Components


SCOPE:



Documents and Publication Comp.

• Documents can occur in different formats

• Publication Components can convert formats into each other and change properties

• PCs: automatic and manual "tools"

SCOPE:



Publication Components (PC)Main Properties (Metadata)• source occurrence (base type + properties) or property • target occurrence (base type + properties) or property• parameters • necessary environment / interfaces• modules / used filesExamples: • autohring tools, conversion scripts, word macros, XSLT

scripts, PDF checker, …

Management system to register PCs and metadata (CVS based)


SCOPE:



Metadata System• special publication component• basic information on each document• adaptable and configurable in terms of

– data model– management processes (forms …)– presentation styles (browsing, search …)

• configuration via XML files and style files• data entry forms can be used

– internally– by extern data managers (editos, by login)– by normal authors (document upload)


SCOPE:



Publishing Process

Formal process model

• assembled with the help of the PC management system(Enquiries to the database …)

• realized and monitored by workflow system

– abstract state machine

– PCs: atomic actions

– integration of external workflow components (e.g. GAPWorks)

• web based – distributed access
